... A rich set of serial devices as well as general-system resources provide enough compute and connectivity capability for many applications. For details on the programming model and theory of operation of each of these units, refer to the Intel® PXA255 Processor Developer's Manual. For the processor block diagram, refer to Intel® ...

... Oscillator” on page 3-4 in the Intel® PXA255 Processor Developers Manual and Section 3.3.2, [2] “3.6864 MHz Oscillator” on page 3-4 of the Intel® PXA255 Processor Developers Manual for details on sleep- mode operation. GPIO sleep operation: The state of these pins is determined by the corresponding PGSRn during the transition into sleep mode. See Section 3.5.9, “ ...

... Float the PXTAL pin or drive it complementary to the PXTAL pin, with the same voltage level, slew rate, and input current restrictions. If floated, some degree of noise susceptibility will be introduced in the system; therefore not recommended. Intel® PXA255 Processor Electrical, Mechanical, and Thermal Specification Table 14 shows the 3.6864-MHz specifications. ...

... On the processor important that the VCCQ power supply be powered up before or at the same time as the VCCN power supply. The VCC and PLL_VCC power supplies may be powered up anytime within the specification shown in 30 Intel® PXA255 Processor Electrical, Mechanical, and Thermal Specification 31. Figure 3 and Table Figure 3, “ ...

... VCC regulator must be stable within the stated maximum for the processor to function correctly. Factors such as external voltage regulator ramp time and bulk capacitance will affect the ramp time of the internal regulator and must be taken into account when designing the system. 34 Intel® PXA255 Processor Electrical, Mechanical, and Thermal Specification t t D_PWR_R ...
